I have a new MPPT 100|30 and using a volt-meter it seems to work fine.
Blue "Bulk"-light is lit, and when I go to the Victtonenergy app on my Android, it finds it and connect and says I need to update from 2.10 to 2.12, fine, I click update, then a progress bar shows up at 1% for some time, then shows:
#11 unknown error occurred.
All I can do is click continue upon when the devices want to restart the whole connection process etc and I end up with the same problem?
What should I do?
